I think the joke is on intel after delivering multiple generations of products with non working linux graphics drivers. This would be akin to Nvidia cracking jokes about thermal solutions.
Don't get me wrong, I haven't yet seen an Intel graphics chipset that I would voluntarily choose again, particularly since I am a heavy user of OpenGL on Linux.
But I still don't think this guy's presentation counts as a fake demo.
And who knows? Maybe someday Intel will deliver a solid product for my purposes.
